The CSO Census of Population and Quarterly National Household Survey (QNHS). Other sources include the Register of Electors, the Child Benefit Scheme, the number of visas granted, the number of work permits issued/renewed, the number of asylum applications, the number of PPS numbers allocated.

Scope

The overall level of the population estimates cover persons resident both in private households and in institutions, but the breakdowns provided are based solely on the QNHS which covers private households only.
From 2007 onwards the population estimates are based on usual residence instead of de facto population.
